Efficient Certificateless Public Key Encryption

Zhaohui Cheng and Richard Comley

Abstract: In [3] Al-Riyami and Paterson introduced the notion of "Certificateless Public Key Cryptography" and presented an instantiation. In this paper, we revisit the formulation of certificateless public key encryption and construct a more efficient scheme and then extend it to an authenticated encryption.
